The Batteries main objective of this paper was to perform sinterability studies of ball-milled Fe-12%Ni-6.4%Cu-1.6%Sn-0.

6%C powders.A mixture of precisely weighed amounts of elemental iron, nickel and graphite, and pre-alloyed 80/20 bronze powders was ball-milled for 8, 30 and 120 hours.After cold-pressing at 400 MPa the specimens were sintered at 900oC for 30 minutes in a reducing Kimonos atmosphere and subsequently tested for density and hardness as well as subjected to structural studies using scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis.
